Evaluation of artificial neural network techniques for river flow forecasting
Environmental Engineering and Management Journal › Vol. 6 › Nr. 1 River runoff forecasting is one of the most complex areas of research in hydrology because of the uncertainty of hydrological and meteorological parameters and scarcity of adequate records. Artificial neural networks (ANN) can be an efficient way of modelling stream flow processes as it is capable of controlling and modelling nonlinear and complex systems and does not require describing the complex nature of the hydrological processes. In this study, daily river flow is forecasted using two ANN ... Autori: Cintia Bertacchi Uvo, Dimitri Namgaladze, George Gabitsinashvili ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=25110

EVALUATION OF HEAVY METALS TOXICITY ON TWO MICROBIAL STRAINS ISOLATED FROM SOIL: Azotobacter sp. AND Pichia sp.
Environmental Engineering and Management Journal › Vol. 11 › Nr. 1 Chromium and cadmium are heavy metals that occur naturally in the environment and especially in soils. Their toxic effect is more pronounced at high concentrations and it depends on the oxidation states. While Cr (III) is considered an essential trace element for the metabolism of living organisms, Cr (VI) has a higher mobility and is easily soluble in soils and can be leached into surface water or groundwater, and taken up by plants. That leads to a toxic and carcinogenic effect to humans via i...
